No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes if it appears likely that such wastes can harm either the sewers, the sewerage system or equipment, or the sewage treatment process or equipment, or have an adverse effect on the receiving stream, or can otherwise endanger life, limb or public property or constitute a nuisance. In forming its opinion as to the acceptability of these wastes, the village shall give consideration to such factors as the quantity of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, the nature of the sewage treatment process, the capacity of the sewage treatment plant, the degree of treatability of wastes in the sewage treatment plant and other pertinent factors. The following substances are prohibited:
(a) Maximum Allowable Temperature Into Sewers or Waterways. Any liquid or vapor having a temperature higher than 140ºF. or 60ºC.;
(b) Maximum Allowable Ether Solubles. Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 80 milligrams per liter ether-soluble or containing substances which may solidify or become viscous at temperatures between 32ºF. and 140ºF., or 60ºC.;
(c) Regulation of Garbage Grinders. Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the village.
(d) Acid and Plating Wastes. Waters or wastes containing strong acid wastes or concentrated plating solutions, whether neutralized or not;
(e) Maximum Metal Concentrations. Waters or wastes containing iron, chromium, copper, zinc or similar objectionable or toxic substances, or wastes exerting an excessive chlorine requirement, to such a degree that any such material received in the composite sample at the waste water treatment works exceeds the limits established by the village. Materials such as copper, zinc, chromium or similar toxic substances shall be limited to the following average quantities in the sewage as it arrives at the waste water treatment plant and at no time shall the hourly concentration at the waste water treatment plant exceed three times the average concentration:
Material
|
Quantity (parts per million) |
Material
|
Quantity (parts per million) |
Arsenic | .05 |
Barium | 2 |
Cadmium | 2 |
Chromium | 1 |
Copper as Cu | 1 |
Iron | 2 |
Lead | 2 |
Mercury | .05 |
Nickel | 2 |
Raw sewage chlorine demand | 12 |
Zinc as Zn | 2 |
Contributions from individual establishments shall be subject to control in volume and concentration by the village.
(f) Permissible Cyanide Levels. Cyanide in excess of one milligram per liter with no dilution and five milligrams per liter with high dilution. Both stated figures shall be regulated at the discretion of the village, using data as the sewage arrives at the waste water treatment plant.
(g) Taste or Odor Causing Substances. Waters or wastes containing phenols or other taste or odor producing substances, in such concentrations exceeding limits which may be established by the village as necessary, after treatment of the composite sewage, to meet the requirements of State, Federal or other public agencies of jurisdiction for such discharge to the receiving waters. Waters or wastes that contain phenols in excess of 0.40 parts per million (400 parts per billion) by weight are prohibited. These limits may be modified by the village if the aggregate of contributions throughout the area of service creates treatment difficulties or produces a plant effluent discharge to receiving waters which may be prohibitive.
(h) Radioactive Wastes. Radioactive wastes or isotopes of such a half-life (over 100 days) or concentration as may exceed limits established by the village in compliance with applicable State or Federal regulations. The radioactive isotopes I13l and p32 used at hospitals are not prohibited if properly diluted at the source.
(i) Corrosive Wastes. Waters or wastes, acid or alkaline in reaction, and having corrosive properties capable of causing damage or hazard to structures, equipment or personnel of the Village Water Pollution Control System, and waters or wastes having a pH lower than 6.0 or higher than 10.0. Free acids and alkalis of such waste must be neutralized at all times. If, after having been duly notified by the village that the wastes are being discharged from any premises, no corrective steps are taken, a penalty charge shall be applied as set forth in § 1034.99(a). It shall be understood that the application of such penalty charge shall in no way relieve any individual, company or industry of any liability for damage to any public or private facility, which damage can be shown to have been caused by the acid or alkaline wastes discharged by such individual, company or industry.
(j) Noxious Substances. Any noxious or malodorous gas or substance which, either singly or by interaction with another waste, is capable of creating a public nuisance or hazard to life or of preventing entry into sewers for their maintenance or repair;
(k) Excessive Waste Concentration. Materials which exert or cause:
(1) Abnormal concentrations of inert suspended solids (including, but not limited to, Fullers earth, lime slurries and lime residue) or inert dissolved solids (including, but not limited to, sodium chloride, calcium chloride and sodium sulfate) from ion exchange softeners;
(2) Excessive discoloration (including, but not limited to, dye wastes and vegetable tanning solutions);
(3) Abnormal B.O.D., C.O.D., suspended solids, phosphorus or chlorine requirements in such quantities as to constitute a significant load on the waste water treatment works; or
(4) Visual volume of flow or concentration of wastes constituting slugs. In no case shall a slug load have a flow rate or contain concentrations or quantities of pollutants that exceed, for any time period longer than 15 minutes, more than three times the average 24-hour concentration, quantities or flow during normal operation.
(l) Nontreatable Wastes. Waters or wastes containing substances which are not amenable to treatment or reduction by the waste water treatment processes employed, or are amenable to treatment only to such a degree that the waste water treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters;
(m) Residues, Sludges and Scums. Any substance which may cause the effluent of the village's waste water plant, or any other product of the plant, such as residues, sludges or scums, to be unsuitable for reclamation and re-use or to interfere with the reclamation process. In no case shall a substance discharged to the village waste water plant cause the waste water plant to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed pursuant to the Solid Waste Disposal Act (42 USC 6901 et seq.), the Clean Air Act (42 USC 7401 et seq.), and the Toxic Substances Control Act (15 USC 2601 et seq.) or state criteria applicable to the sludge management method being used.
(n) Generally. Any substance which will cause the village waste water plant to violate its National Pollutant Discharge Elimination System (NPDES) permit and/or its State disposal system permit or the receiving water quality standards;
(o) Temperature. Any waste water having a temperature which will inhibit biological activity in the village waste water treatment plant resulting in interference, but in no case waste water with a temperature, at the introduction into the waste water plant, which exceeds 85º F. or 30 ºC.; and
(p) Toxic Pollutants. Any waste water containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any waste water treatment process, to constitute a hazard to humans or animals, to create a toxic effect in the receiving waters of the waste water treatment plant or to exceed the limitation set forth in a categorical pretreatment standard.
